Black holes, gravitational waves and fundamental physics: a roadmap
Leor Barack, Vitor Cardoso, Samaya Nissanke +203
The grand challenges of contemporary fundamental physics---dark matter, dark energy, vacuum energy, inflation and early universe cosmology, singularities and the hierarchy problem-…
Determination of new coefficients in the angular momentum and energy fluxes at infinity to 9PN for eccentric Schwarzschild extreme-mass-ratio inspirals using mode-by-mode fitting
Christopher Munna, Charles R. Evans, Seth Hopper +1
We present an extension of work in an earlier paper showing high precision comparisons between black hole perturbation theory and post-Newtonian (PN) theory in their region of over…
Gravitational perturbations and metric reconstruction: Method of extended homogeneous solutions applied to eccentric orbits on a Schwarzschild black hole
Seth Hopper, Charles R. Evans
We calculate the gravitational perturbations produced by a small mass in eccentric orbit about a much more massive Schwarzschild black hole and use the numerically computed perturb…
Scattering of point particles by black holes: gravitational radiation
Seth Hopper, Vitor Cardoso
Gravitational waves can teach us not only about sources and the environment where they were generated, but also about the gravitational interaction itself. Here we study the featur…
Fast spectral source integration in black hole perturbation calculations
Seth Hopper, Erik Forseth, Thomas Osburn +1
This paper presents a new technique for achieving spectral accuracy and fast computational performance in a class of black hole perturbation and gravitational self-force calculatio…
Spin-orbit precession along eccentric orbits for extreme mass ratio black hole binaries and its effective-one-body transcription
Chris Kavanagh, Donato Bini, Thibault Damour +3
In this work we present an analytical gravitational self-force calculation of the spin-orbit precession along an eccentric orbit around a Schwarzschild black hole, following closel…
Analytic self-force calculations in the post-Newtonian regime: eccentric orbits on a Schwarzschild background
Seth Hopper, Chris Kavanagh, Adrian C. Ottewill
We present a method for solving the first-order field equations in a post-Newtonian (PN) expansion. Our calculations generalize work of Bini and Damour and subsequently Kavanagh et…
Eccentric-orbit EMRI gravitational wave energy fluxes to 7PN order
Erik Forseth, Charles R. Evans, Seth Hopper
We present new results through 7PN order on the energy flux from eccentric extreme-mass-ratio binaries. The black hole perturbation calculations are made at very high accuracy (200…
Metric perturbations from eccentric orbits on a Schwarzschild black hole: I. Odd-parity Regge-Wheeler to Lorenz gauge transformation and two new methods to circumvent the Gibbs phenomenon
Seth Hopper, Charles R. Evans
We calculate the odd-parity, radiative () parts of the metric perturbation in Lorenz gauge caused by a small compact object in eccentric orbit about a Schwarzschild bla…
Echoes of ECOs: gravitational-wave signatures of exotic compact objects and of quantum corrections at the horizon scale
Vitor Cardoso, Seth Hopper, Caio F. B. Macedo +2
Gravitational waves from binary coalescences provide one of the cleanest signatures of the nature of compact objects. It has been recently argued that the post-merger ringdown wave…
Unbound motion on a Schwarzschild background: Practical approaches to frequency domain computations
Seth Hopper
Gravitational perturbations due to a point particle moving on a static black hole background are naturally described in Regge-Wheeler gauge. The first-order field equations reduce…
Strong-Field Scattering of Two Black Holes: Numerics Versus Analytics
Thibault Damour, Federico Guercilena, Ian Hinder +3
We probe the gravitational interaction of two black holes in the strong-field regime by computing the scattering angle of hyperbolic-like, close binary-black-hole encounters a…
Strong-field scattering of two spinning black holes: Numerics versus Analytics
Seth Hopper, Alessandro Nagar, Piero Rettegno
We present new Numerical Relativity calculations of the scattering angle between two, equal-mass, black holes on hyperbolic-like orbits. We build upon previous work considerin…
Lorenz gauge gravitational self-force calculations of eccentric binaries using a frequency domain procedure
Thomas Osburn, Erik Forseth, Charles Evans +1
We present an algorithm for calculating the metric perturbations and gravitational self-force for extreme-mass-ratio inspirals (EMRIs) with eccentric orbits. The massive black hole…
